Indeciferable font after loading Turbo Tax

I have some weird fonts on everything ??

I have windows xp, after restarting the computer last night, everything now has this weird font like symbols or something. It's like squares, arrows, & lines, therefore i can't read any thing. I did manage to do a system restore but it would not restore because it said no changes to system have been made. Can anyone help ?
